The story of the word

Greek took νάφθα from Persian, and behind Persian naft stands Akkadian naptu, from a verb meaning to flare up. Dioscorides and Strabo use the word for the flammable seepage around Babylon and the Caspian shore, which the ancient world treated as a marvel and a weapon rather than a fuel. Modern chemistry narrowed it to the light fractions of crude, and the same word is buried inside napalm, coined in 1942 from the naphthenic and palmitic acids used to thicken petrol.
